The decommissioning of nuclear facilities, the productive processing of natural stone and the separation of concrete and reinforced concrete structures pose major challenges for production technology. The solution to these challenges also offers enormous economic potential.
Due to its high performance and cost-effectiveness, abrasive cutting is increasingly used in the natural stone industry, the construction industry, road construction or the deconstruction industry. Abrasive cutting refers to the machining of material by means of geometrically indeterminate cutting edges in order to cut raw materials or to assemble large components into transportable units.
For the natural stone industry, methods are being researched at the IFW in order to make abrasive cutting processes more efficient and flexible and to adapt tools optimally to their cutting task. For this purpose, material removal simulations are used to determine which grain arrangement can achieve the highest removal rate taking tool wear into account.
For the decommissioning industry, processes and tools are adapted to their specific tasks. For example, cross-contamination by dry grinding can be avoided in the dismantling of nuclear facilities. By means of an adapted cooling strategy and suitable selection of process parameters and tools, steel structures can be reliably separated with diamond ropes.
The IFW deals in particular with abrasive cutting in the following projects
DefAhS – Definierter Abtrag hocharmierter Stahlbetonstrukturen
Sekomet – Angepasstes Seilschleifen komplexer, metallischer Strukturen
